BIOSEMIOTICS vs. ANTHROPOSEMIOTICS

Cognitive
Semiotics, Issue 4 (Spring 2009), pp. 116–132

I have clipped what I consider to be
some interesting parts of a very powerful article on the nature of thought:

In this
paper, it will be argued that semiotic cognition can be conceived as a
distinctive form of cognition, which evolved out of earlier forms of non-semiotic
cognition. Semiotic cognition depends on the use of signs and it will be shown
that a sign is not a ‘thing’, but rather the name given to a specific
organization, or structure, of the cognitive process. Once semiotic cognition was available to humans, its structure may have
provided the ground for an evolutionary development that was no longer strictly
Darwinian, but followed its own semiotic logic. Semiotic cognition confronts
humans with a difference that cannot be eliminated, and it is in the ways in
which this difference is dealt with that we may discover a logic of cultural
evolution that determines the course of long term cultural change. (p116)

If we want to explain this absence of meaning and with it the
emergence of a specifically human sense of reality, of time, space, and self,
we have to assume that human cognition is based upon a very peculiar system of
representation (or ‘pattern matching’) which allows us to process what is seen
and heard at the same time, both in terms of stable patterns and of global,
concrete and necessarily ‘fuzzy’ patterns. This double processing generates a difference between the stable
pattern, which corresponds to what we have called memory, on the one hand, and an instable, always changing pattern
corresponding to what one could name the ‘here and now’ or the ‘present’, on the other hand. In a conscious human mind the two
patterns never merge completely. (p122)

[Difference]
may have freed humans from immediacy, from the continuous ‘now’ in which most,
if not all, other organisms live and it probably enabled us to deal with our
environment independently of what is simply ‘the case’ in fantasy, myths,
religion, technology, the arts and sciences, philosophy. These worlds that we
construct in our imagination allow us to cope with change in a more
sophisticated way than other organisms do. It does not take long to figure out
the profit. What distinguishes human cognition and culture from that of other
organisms is not meaning, but the absence of meaning. (p123)

If the
assumption put forward here is correct we may investigate further in two
directions. ‘Backward’, in order to try to find out and explain how such a double
processing could have come about in the evolution of hominids, which is the subject
of evolutionary psychology. And ‘forward,’ to find out if and how the peculiar
structure of human cognition may have influenced the evolution of human
culture. Let us first try to go ‘backward’, finding out about the possible
evolutionary development of the human capacity for double processing. It is
highly probable that this development made use of the strong lateralization of
the human brain. I do not want to
suggest that lateralization caused human culture, but what I do suspect is that
a lateralization, which was already present (and which is related in primates
to handedness*), allowed for the double processing, in terms of stable and
changing patterns, of visual and acoustic information in animals with full
stereoscopic vision, resulting in a 100% identity of the visual input in the two
hemispheres. The coordinating process required a substantial enlargement of the
equally present ‘comparator’ or ‘cockpit’, according to the term coined by
Elkhonon Goldberg. (p123)

The double processing of the stream
of incoming information results in a combination of two types of patterns: stable structures, on the one hand
(which we can now identify as ‘schemata’, ‘scripts’, ‘concepts’, ‘structures’,
or ‘signs’) and a changing situation, on the other hand (identified as
‘reality’, ‘substance’, ‘object’, ‘the thing itself’, etc.). Memories can now
be stored and worked upon independently of the actual situation. Evidently, the
most could be made of this development if the set of available memories were
considerable. Both factors (a large set of memories and a strong comparator)
required brain space. This could be that ‘compelling reason’ why the human
brain got so large between 2 and 1.5 million years ago and why the costs of
such a large brain were worth paying. (p124)

The stable pattern (memory) is related
to a changing pattern (an occurrence). It is this activity of relating that
turns the stable patterns into signs, which are used to recognize (to give form
to, to interpret, to signify) that other more floating set of patterns
constituting actuality. The here and now of the situation, in turn, is what is
not a sign. It is ‘reality’, ‘the world’, ‘the object’. Although we immediately
admit that this too is a construction based on memories. But the difference between the two is not a construction of our memory,
and that is crucial. Thus cognition becomes intentional or semiotic.
(p124-5)

The first step in the evolution of culture,
as we have seen, must have been that of the doubling of the information processing
system: basically the doubling of the representation of perception. (p126)

Semiotic
mimetic actions are fundamentally different from imitations, as imitation
involves the copying of behaviour, whereas mimesis comes with a new way of representing
behaviour, namely without actually performing it (cf. Donald 1991, 2006).
Through mimesis, the stable memories, or signs, are acted out and become
audible and visible.*

*This
corresponds to Piaget’s (1962) notion of “representative imitation”, which
according to him emerges out of sensory-motor imitation, via deferred imitation
(cf. Zlatev 2007).

Human culture is the process in which
more or less stable memories are used to deal with the difference that the
world forces upon us. (p127)

Our identity as human beings is
thus a process in which we continuously investenergy. […] We exist as a set of memories and as aprocess in which these memories
are used to deal with a dynamic environment.I am, we are, ‘in the making’. Viewing the self as a
process rather than as anobject
therefore becomes more natural (Noble 2006). (p128)

Self-consciousness, both individual and collective, is thus
a form ofrecursion;not formal, butsemiotic recursion. Whereas in formal
recursion a form consistsof
elements that reproduce that same form (as in a
triangle consisting of threesmaller triangles, each of which again consists of three smaller
triangles, etc.), insemiotic
recursion the process of representation (of ‘aboutness’) is about thatprocess itself. This is what we
callreflexivity, meta-representation or meta-cognition.The self is always a constructed
self as well as a remembered self or, rather, aself ‘under construction’.
(p128-9)

Moreover,the process as such is again remembered, which gives us a
strongfeeling of being, and having been, alive (cf. Metzinger 2003). […] Art and philosophy are two
importantforms of
meta-cognition in modern and in contemporary culture. Whereas artreflects our life in concrete
images, sounds, and stories, philosophy does sothrough abstract conceptualizations. (p129)

The ‘double processing’ hypothesis presented in this paper
would allow usto shed
light on the evolution of human culture and on cultural evolution aswell. Semiotic cognition became
possible because of a change in the primateinformation processing system.
Once this system was in place, a new logic ofdevelopment could emerge. The logic of cultural evolution
seems to be basedon what
is, in the end, a very simple criterion, namely: whether a sign or signsystem offers better chances of dealing with the difference arising in a specificpersonal, social and natural
context, and in so doing also offers better chancesof prediction and survival. Which brings us back to
biology. This search forbetter
solutions to the problem of difference can explain
individual, social, andgeographical
variations in culture, as well as the steady increase of bothabstraction and cultural
complexity. (p129-30)

Even though culture certainly is a fact of humanbiology, what makes it so
interesting is the fact that out of biology, in this
case,emerges a form ofcognition that became free, at least to a
certain extent, of thelaws of biologyby adding a new dimension to
these laws, namely the dimensionofthe semiotic. (p130)

The approach is deeply and truly Darwinian, in the sense
that it applies Darwin’s perspective where it can and should be applied, and uses
it to explain how and why a non-Darwinian evolutionary system, though nested in
biological evolution and fulfilling the same goals,
could emerge. Neo- Darwinism is fruitful, but only up to a certain point –
which is that of the semiotic. Beyond that point, the laws of development
change: instead of ‘BVSR = Blind Variation + Selective Retention’, the logic of
the semiotic process, involving mimesis, imagination,
conceptualization, and analysis will determine the course of human evolution.*
Whereas selective retention may continue to function as it did in animal life,
cultural variation is not blind, but informed by semiosis and driven by semiotic strategies.**

* Lassègue (2007) develops a related ‘alternative’ view (to
neo-Darwinism, that is), strongly oriented towards the work of Ernst Cassirer.

differences between human and animal cognition are

First things first, that's not a picture of me, although it could be any one of us. It's a painting by Alex Grey.
Next, the blog Limbic Signal is an extension of my book Hidden Scents, and the blog Network Address is a personal archive that I like to keep online for easy access.
Last, I'm a thirty-something male from Suburbia, New Jersey, a high school visual arts instructor, independent researcher, and writer.
Hidden Scents The Language of Smell in the Age of Approximation is my first attempt at authoring a work of non-fiction, and serves as a response to the dearth of information on the topic of Smell.
